MACHINE FORCUTTING AND SWAGING SHOE-TIPS.

ASpecication of Letters Patent No. 29,756, dated August 28, 1860.

To all whom t may concern.'

Be it known that we, HORACE M. BEARCE, of North Auburn, and LEWIS C. PEGK, of Lewiston, both in the county of Androscoggin and State of Maine, have invented a new and useful Machine for Cutting and Swaging Boot and Shoe Tips; and we hereby declare that the following specification, in connection with the y accompanying drawings and references thereon, constitute a lucid, clear, and exact description of the construction and use of ythe same.

In referring to the said drawings, Figure l, denotes a plan or top view; Fig. 2, a side elevation ofthe saine; Fig. 3, a longitudinal vertical section on line A, B, of Fig. l; Fig. et, a front end elevation of our machine.

Invention-. The Vnature of our invention consists in our hereinafter described machine so constructed that it will cutV blanks from sheet metal or any suitable material or substance, and then swage or shape these blanks to conform to, and protect the toes of boots and shoes. These tips being cut from the sheet, and shaped, on our machine at one operation, all as will be hereafter seen.

Construction-. -To enable persons skilled in the art nearest to which our invent-ion appert-ains to construct and carry out the same, we will describe it as follows: We construct a. frame of wood seen at A, in t-he several figures of the drawings. To the top of this frame A, we secure a metal plate seen at B, to the t-op and back end of which we secure two uprights C, by means of screws o. The tops of upright-s are secured by cross bar D, uniting each together by screws e. To the center of cross bar D, is threaded a screw cylinder E, made hollow for the purpose hereafter seen. The screw cylinder E, is turned up or down by balance wheel F, firmly aiixed to its top end.

The front G, of each upright C, is grooved or made a sliding way in which a slide H, is fitted to move up and drop down freely. A die is constructed seen at I, and held in position firmly on plate B, by screws z'. This die has a cavity formed in its upper surface, seen at J, Figs. 1 and 3, the same shape as the tip is designed to be made. To this cavity a metal plunger K is fitted so as to strike, drop, or be moved therein. Its end is of the same shape of cavity J, and less the thickness of material to be worked. The plunger K is secured to slide H, and is moved with, and by it.

The slide H is operated by cam L on main shaft M acting on lower end of rod N or its pulley while its upper end is secured to slide H by stand O. To the upper part of stand lO is secured a rod P around which a helical spring Q `is placed and which is between this stand and lower end of screw cylinder E before described, so that when the slide H is raised and stand O, with it, this spring Q, is brought directly in contact with end of cylinder E to force the plunger K into die I, with greater or less force as may be desired, and thisforced blow may be regulated by turning screw. E up or down at pleasure. Thus by the downward movement and concussive force of plunger K the tip is formed in the die, and to remove the tip after the plunger K is raised out of the die, there is a small rod R, provided and fitted to a hole drilled through the die under the tip. The upper end of this rod is just flush with cavity J in die, its lower end passing down through a guide plate S, on which rests the rod plate T, which has a Spiral or helical spring U between it and upper part of cavity J, in die I. This keeps the rod R always down unless forced up by some superior pressure, which is necessary to apply each time a tip is to be removed which may be done as follows: A rod W is fitted to slide up and down in stands X and Y, the lower portion having a prong Z, guided in stand A2, the prong Z having a pulley B2 so fitted as to come in Contact with cam L (answering for this double purpose) at its under side, so that when the cam L is turned and lets off pulley B2, the spring C2 will throw up rod IV so that its upper end will violently come in contact with lower end of rod R throw it up and consequently throw the tip from the die, the rod R regaining its position by spring U.

Thus far the description is to swaging the tip but prior to that the blank for each tip must be cut from the sheet and deposited in the die I at the right moment. IVe secure two guide pieces D2 to uprights C. Between these we fit a slide E2 to move vertically or nearly so by its arm F2, connected by rod G2 with eccentric H2 on main shaft M on which the balance or drive wheel I2 is placed. The slide E2 is, provided with a cutter J2 and stamp K2. Underneath these we erect a stand seen at L2, in which the die holder h 2 is placed adjustably by screws a2. The die holder M2 carries die N2 the top of which is placed on an angle so that the cutter J2 will cut the blank a shearing stroke. Of course the cutter and the hole in its die must be shaped as the blank is required to be. The stamp K2 stamps the next contiguous blank o-n the sheet the date of patent of tip.

The guide is seen at O2, and is secured to plate B, by screws a3. This guide gages the distance or relation of the sheet A4 to the cutter J2 and must be set each time a row of tips is cut from the edge of the sheet seen in red line A4. After the blank is cut, it drops through die N2 into tube P2 of stand Q2 and down forward of slide bar R2 and by this bar is forced forward over cavity J, in die I, to be set, and the movement must be so timed as that the cutting and setting will harmonize with each other. The slide bar R2 moves in stand S2 and channel in die I and the movement imparted to it by its pin at and the forked rod T2 swinging on stand U 2 its lower end having a pulley V2 which comes in contact with and is operated by cam V2 on mainyshaft. The pulley V2 is kept against cam by spring X2.

Fig. 3 represents our machine with a tip just formed in die I and the other figures represent the plunger K raised and the cutter J2 cutting the blank from sheet A2 which is fed along by hand.

'ting the blank when combined with die I for swaging the tip essentially as set forth.

3. The combination of the tube P2, stand Q2 and slide bar R2 operated by cam or otherwise, to receive and feed the blanks direct from the cutting die to the swaging di'e, essentially as set forth.

4. The rod R and its plate T, guide plate S and helical spring U combined with die I, the rod R being operated by percussive force to throw the swaged top from the die, essentially in the manner and for the purposes fully set forth.
